Ankle support is a kind of equipment to protect the human ankle joint, suitable for badminton, tennis, football, bicycle, dance and other sports, or for ankle joint inversion injury, postoperative fixation and strength protection during rehabilitation. In mild ankle sprains, the ligaments are loosened or partially torn; in severe cases, the ligaments are completely ruptured, with subluxation of the ankle joint, or complicated by fracture and dislocation. After ankle sprain, the patient has pain and swelling in front of or below the outer heel, and there may be ecchymosis in the acute stage. At this time, the movement of foot inversion will aggravate the pain, and the foot inversion can be painless.There are many reasons for ankle sprains, such as insufficient preparation; uneven sandy ground; bad sneakers; lack of concentration when exercising; stepping on the ball when jumping and running, and running on uneven roads will hurt the ankle the most. [1]Diagnosis is easier, and a preliminary diagnosis can be made based on the history of trauma and symptoms and signs. But to identify the severity, and then make a correct diagnosis. Generally speaking, if you have pain when you move your ankle, but it is not severe, it is mostly a soft tissue injury, and you can treat it yourself. If you have severe pain when you move your ankle, you can't stand or move, the pain is on the bone, there is a sound when you sprain, and it swells quickly after the injury.For less severe ankle sprains, immediate cold compresses (10-15 minutes in cold water) will reduce pain, prevent excessive swelling and help prevent bleeding inside the tissue. If ice cubes are used, they should not be in direct contact with the skin, otherwise it may burn the skin, so wrap the ankle with gauze. Hot and cold water basins can be beneficial for ankle sprains, from stimulating blood supply to quickest healing and reducing swelling. Put your heels in a tub of hot water at the right temperature for about 15 seconds, then switch to a tub of cold water for about 5 seconds, and so on. As a lightweight ankle protective orthosis, the ankle brace is suitable for patients with frequent ankle sprains, ankle ligament injuries, and ankle instability. It can effectively provide cushioning for the ankle during exercise, which can limit the left and right movement of the ankle, prevent sprains caused by inversion and inversion of the ankle, reduce the pressure on the injured part of the ankle joint, strengthen the ankle joint and promote the recovery of the injured soft tissue. Moreover, it can be used with ordinary shoes without affecting the walking gait.Ankle injuries are one of the most common sports injuries. Injuries to the ankle are more common in running, jumping, or changing direction. The ankle twists beyond the individual's range of motion, overstretching and tearing the ligaments around the ankle joint, as well as damage to the extensor digitorum muscle belly and tendon. Tendon and muscle belly; tendon and bone junction is the most prone to injury. The foot and ankle are complex mechanisms. There are many foot-attached joints, many of which are fretting joints. The weak link of the foot and ankle joint is the main part of sports injuries.If the muscles, tendons, and ligaments around the ankle are not adequately trained and are in a weak state, there is a risk of injury. For example, the calf muscles may be stronger than the overall calf muscles, which can lead to muscle imbalances. Or the Achilles tendon is too tight and the muscles in front are too flexible, which leads to an imbalance in flexibility. The second is the lack of warm-up and muscle-stretching activities. Support straps can provide additional support and stability for weak and injured ankle joints.
